Overview
The GE AKTA Explorer 100 is a high-performance, benchtop preparative liquid chromatography system engineered for robust method development and scalable purification of biomolecules—including monoclonal antibodies, recombinant proteins, plasmids, and viral vectors. Designed under GE Healthcare’s legacy (now part of Cytiva, with full platform continuity maintained by Baker Hughes’ life sciences instrumentation division), the AKTA Explorer 100 implements low-pressure gradient chromatography based on precision peristaltic pumping, real-time UV/Conductivity/pH/temperature monitoring, and integrated fraction collection. Its architecture supports both analytical-scale screening and early-stage process development, delivering reproducible retention time, peak shape, and resolution across repeated runs—critical for establishing transferable purification protocols compliant with ICH Q5A/Q5B and regulatory expectations for biopharmaceutical characterization.
Key Features
- Integrated BufferPro module for fully automated online buffer preparation: dynamically blends stock solutions of acid, base, salt, and water to generate precise pH and ionic strength gradients—eliminating manual titration and reducing buffer optimization time by up to 30 minutes per condition.
- UNICORN 6 software with embedded Design of Experiments (DoE) engine: enables multivariate parameter optimization (e.g., pH, conductivity, gradient slope, flow rate) in minimal experimental runs—supporting statistical modeling, interaction analysis, and robustness assessment per ICH Q8(R2) principles.
- Method Editor with drag-and-drop workflow: allows intuitive creation of multi-step chromatographic methods via preconfigured stage templates—retaining full script-level control for advanced users while accelerating method setup for new operators.
- Dual pressure sensing at column inlet and outlet: continuously calculates ΔP across the packed bed, enabling real-time column integrity monitoring, pressure-limited flow control, and safe operation within validated pressure limits of Capto™, MabSelect™, and other BioProcess™ resins.
- UNICORN 6 compliance with FDA 21 CFR Part 11: includes electronic signatures, role-based access control, immutable audit trails, and secure electronic records—fully supporting GLP/GMP environments and regulatory submissions.
- UniTag-enabled column tracking: QR-coded identification of prepacked columns (e.g., HiScreen™) or user-packed columns; automatically logs run history, cumulative cycles, max ΔP, cleaning intervals, and maintenance alerts—ensuring full traceability per ALCOA+ data integrity standards.
Sample Compatibility & Compliance
The AKTA Explorer 100 accommodates a broad range of sample types—from clarified mammalian cell culture harvests and bacterial lysates to purified protein pools and nucleic acid fractions. It supports standard chromatographic modes including ion exchange (IEX), size exclusion (SEC), hydrophobic interaction (HIC), and affinity chromatography (e.g., Protein A). All fluidic pathways are constructed from bio-inert materials (PEEK, stainless steel, PTFE) compatible with common sanitizing agents (NaOH, ethanol, isopropanol) and low-pH elution buffers. The system meets ISO 9001-certified manufacturing requirements and operates within specifications aligned with ASTM E2500-13 (Good Automated Manufacturing Practice) and USP Analytical Instrument Qualification guidelines.
Software & Data Management
UNICORN 6 serves as the central control, acquisition, and reporting platform. All chromatograms, sensor data (UV, conductivity, pH, temperature, pressure), and fraction metadata are stored in a single, tamper-evident SQLite database with automatic daily backups. Audit trails record every user action—including method edits, parameter changes, start/stop events, and electronic signature applications—with timestamps and operator IDs. Validation support packages—including IQ/OQ documentation templates, test scripts, and configuration files—are available through Baker Hughes’ Regulatory Support Services. Data export complies with CDISC SDTM and CSV/Excel formats for integration into LIMS or statistical analysis platforms (e.g., JMP, SIMCA).
Applications
- Rapid screening of binding/elution conditions for mAb purification using HiScreen™ columns (1–10 mL bed volume).
- DoE-driven optimization of polishing steps (e.g., flow-through anion exchange) to maximize host cell protein clearance while preserving yield.
- Buffer scouting across pH 3.0–9.0 for viral vector purification under mild conditions.
- Column lifetime studies with automated ΔP logging and cleaning-in-place (CIP) cycle tracking.
- Preparative SEC analysis of aggregate profiles in biosimilar comparability studies.
- Method transfer verification between AKTA Explorer 100 (R&D scale) and AKTA avant 25/150 (pilot scale) systems.
FAQ
Is the AKTA Explorer 100 compatible with modern BioProcess™ resins such as Capto Core 700 or MabSelect PrismA?
Yes—the system’s pressure rating (max 20 bar), flow range (0.01–100 mL/min), and gradient precision fully support all Cytiva/Baker Hughes BioProcess™ resins, including high-flow, low-backpressure media.
Does UNICORN 6 support automated method generation from DoE output?
Yes—DoE results can be directly exported to Method Editor to auto-generate optimized gradient and step methods, including conditional logic for pH-triggered elution.
Can the system operate unattended overnight with full data integrity assurance?
Yes—UNICORN 6 supports scheduled runs, password-protected method locking, and continuous audit trail logging—even during extended无人值守 operation.
What validation documentation is provided with a refurbished AKTA Explorer 100 unit?
Each unit undergoes full functional testing per Baker Hughes’ Used Equipment Requalification Protocol (REF: AKTA-UEP-2023), including pump accuracy, detector linearity, fraction collector positioning, and sensor calibration verification—documentation delivered digitally upon shipment.
Is UniTag scanning hardware included with the system?
Yes—a USB-connected QR code scanner is supplied; UniTag labels (pre-printed or custom-printed) are required for unlabeled columns and are available through Baker Hughes’ consumables catalog.
